Why It's a Seed-Starting Essential:

  • Double the Capacity: This 16-quart bag provides twice the volume of our standard size, making it ideal for gardeners starting a diverse variety of heirloom tomatoes, peppers, and summer annuals.

  • Superior Germination Rate: Its extra-fine, screened texture allows even the smallest seeds to sprout and push through without resistance.

  • Root-Boosting Ingredients: Enriched with mycorrhizae, worm castings, and kelp meal to help young plants develop deep, strong root systems right from day one.

  • Moisture Management: The blend of sphagnum peat moss and perlite prevents the soil from compacting while holding just enough water to keep your seeds hydrated without over-saturating them.

  • OMRI Listed: 100% organic, ensuring your home-grown food starts in the cleanest environment possible.
